Energy and sustainability

The Fraunhofer FEP offers innovative technologies and solutions in the field of energy and sustainability that contribute to increasing efficiency and conserving resources.

In the field of photovoltaics, the institute develops advanced coating processes to optimize solar cells and modules. For hydrogen technology, precise thin-film depositions for electrolysers are used to increase the efficiency of hydrogen production. We also develop customized coatings for battery technologies to improve the performance and service life of energy storage systems. The Fraunhofer FEP is also working on intelligent solutions for energy management to support sustainable and efficient energy systems.

• Metallized polymer films as current collectors in roll-to-roll technology
• Deposition of solid-state electrolyte layers
• Development of nodular silicon layers using roll-to-roll processes
• Thermal vapour deposition of lithium thin films on metal substrates and pre-lithiation of anodes
• Development of a novel technology for the production of electrochemical energy storage systems as an alternative to lithium-based battery systems for aluminium batteries
• Development of a solid-state battery for mobile high-valent ions
• Development of a production technology for solid-state electrolytes and electrodes

The Fraunhofer FEP is aware of its social responsibility as a research institute. Awareness of resource-conserving behaviour in research and development and in the interests of our customers is an important aspect of our projects. 

In 2016, the energy management system was introduced in accordance with DIN ISO 50001 and has been regularly recertified since then. The energy management system creates transparency regarding energy flows and increases energy efficiency during institute operations. 

Selected measures:

• Installation of heat pumps for waste heat utilization to save heating and cooling energy
• Integration of a weather forecasting station into the building management system to reduce the heat energy consumption of the entire institute.
• Installation of photovoltaic systems with nominal outputs of between 43 and 87 kWp.
• Use of controllable electronic thermostatic valves in office and technical center buildings.
